Apple Addresses Two Exploited Zero-Day Vulnerabilities in macOS Sequoia
Apple has taken a significant step to enhance the security of its macOS Sequoia operating system by disclosing and patching two recently discovered zero-day vulnerabilities that were actively exploited in the wild. These vulnerabilities, tracked as CVE-2024-44308 and CVE-2024-44309, were addressed in the latest security update, which was released on Tuesday for version 15.1.1 of macOS Sequoia. This update underscores the growing concerns surrounding cybersecurity, particularly as attacks targeting Mac devices become more prevalent.
Discovery and Vulnerability Details
The vulnerabilities were identified by security engineers Clément Lecigne and Benoît Sevens from Google’s Threat Analysis Group (TAG). Both flaws are triggered when users interact with malicious web pages, posing a significant threat to users who inadvertently visit infected sites.
- CVE-2024-44308: This vulnerability allows for arbitrary code execution, posing risks that could lead to severe data breaches and system compromises.
- CVE-2024-44309: This is related to cross-site scripting (XSS) attacks, which can enable attackers to inject malicious scripts into web pages viewed by other users.
In the advisory published by Apple, the company acknowledged reports that these vulnerabilities may have been actively exploited on Intel-based Mac systems, signaling an urgent need for users to update their software to the latest version.
Technical Remediation
To mitigate these security risks, Apple implemented several fixes. For CVE-2024-44308, the solution entailed enhancing checks within JavaScriptCore, whereas CVE-2024-44309 was corrected by addressing a cookie management issue in WebKit through improved state management. Typical of Apple’s security advisories, details of the vulnerabilities remain limited, which may conceal the full extent of their impact.
The vulnerabilities are not limited to macOS Sequoia; they were also addressed in Safari 18.1.1, iOS 17.7.2, iOS 18.1, iPad 18.1, and visionOS 2.1, as noted by a Tenable blog post detailing the updates.
Rising Threats to macOS Users
In light of the increasing number of macOS-targeted attacks, several cybersecurity firms have highlighted this alarming trend in recent months. A blog post from Trellix, titled "MacOS Malware Surges as Corporate Usage Grows," emphasized a noticeable shift in ransomware and malware targeting the Mac platform. This change in strategy has risified the threat landscape for those utilizing macOS devices within corporate environments.
Laura Brosnan, a senior information security specialist at Red Canary, reflected similar sentiments in her own analysis, underscoring the misconception that macOS systems are immune to malware. “In fact, many people still hold the belief that macOS is immune to malware—a dangerous misconception. However, 2024 has shattered that illusion,” Brosnan remarked.
Industry Response and Recommended Actions
In response to the escalating crimeware activities targeting Mac users, SentinelLabs has urged all macOS users, especially those within organizations, to bolster their security protocols and heighten their awareness of potential cyber threats. Practicing safe browsing habits, regularly updating software, and employing robust cybersecurity measures are essential in the current volatile landscape.
The surge in attacks on macOS devices aligns with a broader trend affecting various platforms, emphasizing the importance of maintaining vigilant cybersecurity practices. With advanced persistent threat (APT) actors, such as the notorious Lazarus Group from North Korea, now focusing on these systems, the urgency for users to take protective measures has never been higher.

Welcome to the World-Today News website. Let’s start the interview by discussing the two zero-day vulnerabilities that were recently discovered in macOS Sequoia and how they were exploited:
Guest 1: Can you please introduce yourself and your role in the industry?
Guest 2: Sure, I’m Sarah, a cybersecurity analyst at a leading software company. I specialize in keeping our users informed about emerging threats and advising them on how to stay safe online.
Guest 1: Great, thanks for joining us today, Sarah. To begin with, can you explain the severity and impact of these vulnerabilities?
Sarah: Absolutely. Apple recently addressed two zero-day vulnerabilities, tracked as CVE-2024-44308 and CVE-2024-44309, which were being actively exploited in the wild. The first vulnerability, CVE-2024-44308, allows for arbitrary code execution, posing severe risks to data breaches and system compromises. The second one, CVE-2024-44309, is related to cross-site scripting (XSS) attacks, which enables attackers to inject malicious scripts into web pages viewed by other users. These vulnerabilities can be triggered when users interact with malicious web pages, making them a top priority for patching.
Guest 1: That’s concerning to hear. How did Apple respond to these threats?
Sarah: Apple released security updates to address these vulnerabilities in macOS Sequoia version 15.1.1 on Tuesday. They also released patches for Safari, iOS, iPadOS, and watchOS to ensure that users across all platforms are protected. It’s essential for users to update their systems as soon as possible to minimize the risk of being exploited. Apple has been quite responsive in addressing these threats, which is crucial in maintaining the security of their operating systems.
Guest 1: As macOS systems become increasingly popular, we’ve seen a surge in attacks targeting them. How do you think this affects users who might have become complacent about the safety of their Mac devices?
